CARBURETEB.

Specification of Letters Patent.

Patented Jan 5, 1915.

Application filed February 1, 1918. .Serlal No. 745,630.

To all whom it may concern:

Be it known that I, ,Asnnnr C. BENNETT,

a citizen ofthe United States, residing at Minneapolis, in the county of Hennepin and a State of Minnesota, have invented certain new and useful Improvements in Carbureters, .of which the followingis' a specification.

My invention relates .to carbureters, and has for its object to rovide means for in ereasin the distributing or vaporizing area of the uel feed, so that relatively heavy fuel oils may be completely vaporized and a higher degree of vaporizing efficiency be made possrble for all'forms of fuel oils.

The full objects and advantages of my invention will appearin connection with the detailed descriptionthereof and are particularly pointed out in the claims In the drawings, illustrating the application of my invention in one form, Figure 1 is a sectional view ofa'partof a carburetor v ng my impro ement applied thereto. Fig. 2 isasectiqn ofthe; pi showing one of the .spreaders in plantx ig. 8 is a front elevationfof a portionfoftlie feed pipe.

As shown, a'rasing P10 is; formed with a chamber 11 to whichjthe fuel oil is fed from the supplytank in a wellilmown manner. From t e chamber 11 a passageway 12 intercepts' transversely zapassageway '13 openintoa vertical. f pipel, said openbeing controlled by a needle valve 15.

' A out the bottom of the feed pipe 14 is a cup 16, and the feed ipe is provided with a series of apertures a ong one side thereof. The feed pipe is located in'a chamber 17 formed by the casing 10 and separated from the fuel reservoir or chamber 1-1.. A primaryjir'inlet port 18 is provided, and also'a secondary air inlet port 19 is provided; the} port 18 being at all times open to its full extent and operating to admit air under slow speeds, While the port 19 is closed by a valve 20 which may be positioned by means such construction, l arrange upon the feed pipe 14 a series of double fins 23 having an outline view similar to that shown in Fig. 2-,

the parts of said fins being secured together at t e edges 24 and 25, and fiaringtoward the center, as clearly shown in Figs. 1 and 3. Each of these double fin members 23 is strung 'uponthe feed pipe 14-, so that the parts thereof fall on opposite sides of the apertures in a I given horizontal plane formed 1n feed'pipe 14, the said double tin members being soldered, or Otl'lBlWlSO seuum created withinchamber'l'? draws fuel oil through apertures 21, beginning first to draw through the bottom aperture, and, as 4 the speed of the enginedncreases sows-to correspondingly increase the .vacuum formed, the fuel oil will rise inthe feed pipe 14, and feed through'apertures 21fisuccessively higher'up the-feed pipegfintil if the speed of the engine 'become lsulliciently high, it may cause oil t0.'b6 drawn-through all of said apertures. passes out of said apertures, it does not immediately spray into the'cnrr ent of air but flows along the inner walls of the fin members 2,3, spreadin radially until-it reaches the outer edges" of said 'fin' members or spreaders, where it contacts with the current of air passingthrough chamber 17. The same amount/0f fuel oil, therefore, which would be brought into coritfact with the current of .air at a single point eorre' spending in area to thearea of anaperture 21, is now spread out so-that con tact'with When the, fuel oil the air takes place throughout an extent I as described and claimed in my co-pending thin film, from which the breakingup into application No. 706,908, filed Jilly 1st, 1912,

sotllat port 19 is opened varying degrees for the admission of what is known as secture to the engine cylinders. In my present.

the side of. feed va'por particles can be most efi'ectivelyaecompli shed.

In the practice of my invention it is not essential that the fin members 27 shall cornlee prise rpm of plates secured together at one set of edges, as single plates with the fuel discharge upon the surface thereof wilL answer the purpose almost as well. Even where the double plates are used apertures such as 21 may be provided in the feed pipe 2O pl side. 6f said v t lb -1:
